导出excel按动态表头导出

一、实现代码使用Map方式添加head头，对应填充值

  /*** 导出查看发车明细* @param query* @return*/@Overridepublic ExportResult monthResourcePlanDepartureProgressDetailsExportExcelData(ResourceSituationListQuery query) {log.info("导出参数:{}",DstJsonUtil.toString(query));//List<ResourcePlanShipDetailVO> shipDetail = resourcePlanService.getShipDetail(query);List<ResourcePlanShipDetailVO> shipDetail = resourceSituationCoreService.getCodData();if (CollectionUtils.isEmpty(shipDetail)) {log.error("导出数据为空");return null;}List<String> dispatchDate = new ArrayList<>();shipDetail.stream().forEach(e->{e.getShipDetails().stream().forEach(it->{dispatchDate.add(DstDateUtil.format(it.getDispatchDate(),DstDateUtil.Y_M_D));});});List<String> newDispatchDate = Lists.newArrayList(new HashSet(dispatchDate));List<String> newDispatchDateList = newDispatchDate.stream().sorted().collect(Collectors.toList());List<String> monthAndDays = new ArrayList<>();for (String date : newDispatchDateList) {monthAndDays.add(date);}List<String> headers = new ArrayList<String>() {{add("数据类型");add("资源情况编码");add("关联发车计划编码");add("大区城市");add("车辆品牌（属性）");add("车辆型号（属性）");add("车型族群（属性）");add("电池包度数（属性）");add("电池包厂商（属性）");add("车辆用途（属性）");add("发车总数");addAll(monthAndDays);}};List<String> columns = new ArrayList<String>() {{add("dataType");add("resourceSituationCode");add("shipCode");add("cityName");add("carBrandName");add("carModelName");add("carModelGroupName");add("esdTotalPowerName");add("esdCompanyName");add("vehicleUseName");add("needShipCountTotal");addAll(monthAndDays);}};List<Map<String, Object>> mapDatas = new ArrayList<>();shipDetail.forEach(p -> {mapDatas.add(converItemToMap(p,1,monthAndDays));mapDatas.add(converItemToMap(p,2,monthAndDays));});return ExportResult.wrap(headers, columns, mapDatas, 1);}

二、核心转换方法

/*** @Description 转换map* @Param item type 1:计划发车 2:实际发车* @Return java.util.Map<java.lang.String,java.lang.Object>* @Date 2024/3/12 18:59* @Author lwp*/private Map<String,Object> converItemToMap(ResourcePlanShipDetailVO item,Integer type,List<String> monthAndDays){Map<String,Object> temp =new HashMap<>();String dataType = type == 1 ? "计划发车" :"实际发车";Integer needShipCountTotal = type == 1 ? item.getTotalAssignCount() : item.getTotalShipCount();temp.put("dataType", dataType);temp.put("resourceSituationCode",item.getResourceSituationCodes());temp.put("shipCode",item.getShipCodes());temp.put("cityName",item.getFullCityName());temp.put("carBrandName",item.getCarBrandName());temp.put("carModelName",item.getCarModelName());temp.put("carModelGroupName",item.getCarModelGroupName());temp.put("esdTotalPowerName",item.getEsdTotalPowerName());temp.put("esdCompanyName",item.getEsdCompanyName());temp.put("vehicleUseName",item.getVehicleUseName());temp.put("needShipCountTotal",needShipCountTotal);item.setShipDetails(item.getShipDetails().stream().sorted(Comparator.comparing(AssignDetailVO::getDispatchDate)).collect(Collectors.toList()));for (String monthAndDay : monthAndDays) {A: for (AssignDetailVO shipDetail : item.getShipDetails()) {String dispatchDate = DstDateUtil.format(shipDetail.getDispatchDate(), DstDateUtil.Y_M_D);if (dispatchDate.equals(monthAndDay)) {temp.put(monthAndDay, type == 1 ? shipDetail.getDispatchNum() : shipDetail.getShipCount());break A;} else {temp.put(monthAndDay, type == 1 ? 0 : 0);}}}temp = MapUtils.sortMapByKey(temp);return temp;}

三、导出实体类

package com.dst.steed.fulfillment.common.domain.biz.resourceplan;import com.dst.steed.common.convert.translation.Translation;
import lombok.Data;import java.util.List;/*** 资源计划发车明细*/
@Data
public class ResourcePlanShipDetailVO {/*** 资源情况编码*/private String resourceSituationCodes;/*** 发车计划编码*/private String shipCodes;/*** 城市编码*/@Translation(convertName = "convertRegionAndCityName", convertTo = "fullCityName")private String cityCode;/*** 城市名称*/private String fullCityName;/*** 车辆品牌*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-carBrandName")private String carBrand;private String carBrandName;/*** 车辆型号*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-carModelName")private String carModel;private String carModelName;/*** 车型族群*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-carModelGroupName")private String carModelGroup;private String carModelGroupName;/*** 动力电池包电量*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-esdTotalPowerName")private String esdTotalPower;private String esdTotalPowerName;/*** 动力电池包厂商*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-esdCompanyName")private String esdCompany;private String esdCompanyName;/*** 资产分类*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-assetClassifyName")private String assetClassify;private String assetClassifyName;/*** 车辆用途*/@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-vehicleUseName")private String vehicleUse;private String vehicleUseName;/*** 发车总计-计划发车量*/private Integer totalAssignCount;/*** 发车总计-已发车量*/private Integer totalShipCount;/*** 发车总计-剩余量*/private Integer totalResidueCount;/*** 发车明细*/private List<AssignDetailVO> shipDetails;
}

实体类属性明细类

package com.dst.steed.fulfillment.common.domain.biz.resourceplan;import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;import java.util.Date;/*** 分配详情VO*/
@Data
public class AssignDetailVO {/*** 中心分配ID*/private String id;/*** 分配类型 1. 中心分配 2. 大区分配*/private Integer referenceType;/*** 发车日期*/@JsonFormat(pattern = "M月d日", timezone = "GMT+8")private Date dispatchDate;/*** 中心分配发车数量*/private Integer centerDispatchNum;/*** 城市计划发车数量*/private Integer dispatchNum;/*** 实际发车数量(发车明细字段)*/private Integer shipCount;
}
